Hydrogen Material: - Production of hydrogen properties of hydrogen Why is hydrogen unique Test for hydrogen Uses of hydrogen
Production of hydrogen As the reaction between a metal and acid produces hydrogen, we can place this reaction in a flask that is connected to a delivery tube, that will allow hydrogen to pass through it ending up in a water trough, hydrogen will try to escape by bubbling up into the glass jar
Properties of hydrogen Colorless: - can t be see Odorless: - has no small Tasteless: - doesn t have a taste Gas: - found in gas state, not liquid, or solid Lightest gas: - least density, lighter then air Explosive: - H2 + O2 H2O + energy reactants combine causing an explosion
Why is hydrogen unique? Hydrogen is knows as a very unique element as: - 1) It is a non-metal in group(I) - Usually elements in group(I) are metals 2) It tends to form more than one ion - H1+ is non as a proton (stable) - H1- is known as a hydride (unstable)
Test for hydrogen A boy forgets to label contents of 2 tubes, but he remembers that one of them has hydrogen, and the other has carbon dioxide The problem is that their both 1) Odorless 2) Colorless 3) Tasteless 4) Gas He asks his teacher, how do I test for hydrogen? , and the teacher answers him Test: - expose the gas to a lighted splint (in the presence of oxygen) Result: - it ll explode with a squeaky pop sound The equation for the rxn is as follows: - H2 + O2 H2O + energy
Uses of hydrogen Hydrogen is a very useful gas 1) It is used as a fuel 2) It makes ammonia, NH4 (a soil fertilizer) - 3H2 + N2 2NH4 3) It is used to make plastic (PV) 4) It also turns liquid vegetable oils into margarine
